ive been using the MTR'S for 2 years now, as my daily driver, and ive put almost 40,000k on them driving back and forth from calgary to forx creek, grande cashe, etc, and i'd definately buy them again. there is still 90% tread left, they're great in mud, and on snow and ice. just a reminder, mine are 35's, but dont pressure the tires to 35 psi, im running mine at 28 [psi, and they're doing fine.
